The Kepler Mission, NASA Discovery mission #10, is specifically designed to survey our region of the Milky Way galaxy to discover hundreds of Earth-size and smaller planets in or near the habitable zone and determine how many of the billions of stars in our galaxy have such planets.

Date: Oct 4, 1940 Construction of the 16ft (high speed) Wind Tunnel. Of the original tunnels planned for Ames the 16ft had perhaps the highest priority. Assigned this precedence because it was to have a higher spped than any other major wind tunnel in the NACA and would provide aerodynamic data at speeds at which future military airplanes were expected t fly. It operated at speeds up to 680 mph, about 0.9 of the speed of sound and 4 times the cross-sectional area of the Langley 8ft tunnel. Its...
Photographer: JPL These four pictures of Jupiter's Great Red Spot were taken Feb. 2 and 3, 1979, when Voyager 1 was about 31 million kilometers (19.4 million miles) from Jupiter. The pictures were taken one Jupiter rotation apart, so that together they depict four days in the life of the centuries-old Red Spot. The pictures clearly demonstrate changes in circulation around the Red Spot during the 40-hour period. The photos were taken through a blue filter. Jet Propulsion Laboratory manages the...

Photographer: JPL P-21735 BW This Jupiter image taken by Voyager 2 shows an area from 10 _ N. Lat. to 34 _ S. Lat. in a region west of the Great Red Spot. At the top of the picture, equatorial plumes are seen. These features move along the edge of the equatorial zone. The remainder of the equatorial region is characterized by diffuse clouds. The region west of the Great Red Spot is seen as a disturbed wave-like pattern. Similiar flows are seen to the west of the white oval at bottom.

Photographer: JPL P-21745 BW Range: 1.1 million miles (675,000 miles) This image of Callisto taken by Voyager 2 was enhanced to reveal detail in the scene. Voyager 1's high resolution coverage was of the hemisphere just over the right-hand (eastern) horizon, and the large ring structure discovered by Voyager 1 is just over the eastern limb. This image shows yet another ring structure in the upper part of the picture. Callisto exhibits some of the most ancient terrain seen on any of the...

Photographer: JPL P-21747 BW Range: 2,200,000 miles This image shows a region of the Jovian atmosphere from approximately 25 _ N to the equatorial region. The north temperate jet, at approximately 23 _ N, where the wind speed is about 150 meters per second, is seen as a dark brown line from the left-hand edge to the right-hand corner of the picture. The wispy clouds of the north equatorial belt appear as shades of brown. The lower right-hand corner of the image shows the brighter (white) clouds... Topic: Where -- Jet Propulsion Laboratory (JPL)
Photographer : JPL This color reconstruction of part of the northern hemisphere of Ganymede was made from pictures taken at a range of 313,000 km (194,000 mi.). The scene is approx. 1,300 km (806 mi.) across. It shows part of dark, densely cratered block which is bound on the south by lighter, and less cratered, grooved terrain. The dark blocks are believed to be the oldest parts of Ganymede's surface. Numerous craters are visible, many with central peaks. The large bright circular features...

5:30 pm PDT Photographer : JPL Range : 1,550,000 km ( 961,000 miles ) These high resolution pictures of Jupiter's ring were obtained by Voyager 2 some 26 hrs. past the planet, 2 degrees below the ring plane. The forward scattering of sunlight reveals a radial distribution and density gradient of very small particles extending inward from the ring toward Jupiter. There is an indication of structure within the ring, but unfortunatly the spacecrafts motion during these long exposures blurred out...

Photographer : JPL Range : 3.2 million km This image returned by Voyager 2 shows one of the long dark clouds observed in the North Equatorial Belt of Jupiter. A high, white cloud is seen moving over the darker cloud, providing an indication of the structure of the cloud layers. Thin white clouds are also seen within the dark cloud.

Photographer : JPL Range : 3.4 million km This pair of images shows two of the long-lived white oval clouds which have resided in the Jovian southern hemisphere for nearly 40 years. The upper picture shows the cloud that is at a longitude west of the Great Red Spot, and the lower frame, the cloud at a longitude east of this feature. The third oval is currently just south of the Great Red Spot. The clouds show very similar internal structures. To the east of each of them, recirculation currents...

Photographer : JPL Range : 4.1 million km. ( 2.5 million miles ) P-29466B/W Voyager 2 has discovered two "shepard" satellites associated with the rings of Uranus. The two moons, designated 1986U7 and 1986U8, are seen here on either side of the bright Epsilon Ring. All nine of the known Uranian rings are visible here. The image was proccessed to enhance narrow features. The Epsilon Ring appears surrounded by a dark halo as a result of this proccessing. Occasional blips seen on the ring...

Photographer: JPL P-29509 BW Range: 500,000 kilometers (300,000 miles) This high-resolution image of Titania was made as Voyager 2 neared its closest approach to Uranus. Voyager's narrow-angle camera acquired this image through the violet and clear filters and shows details about 9 km (6 mi) in size. Titania has a diameter of about 1,600 km (1,000 MI). In addition to many scars due to impacts, Titania displays evidence of other geologic activity at some point in its history. The large...

Photographer: JPL P-29512 BW Range: 36,000 kilometers (22,000 miles) Miranda, innermost of Uranus' large satellites, is seen at close range as part of a Voyager 2 high-resolution mosaicking sequence. This clear-filter, narrow-angle image shows an area about 250 km (150 mi) across, at a resolution of about 800 meters (2,600 feet). Two distinct terrain types are visible; a rugged, higher-elevation terrain (right) and a lower, striated terrain. Numerous craters on the rugged, higher terain...

Photographer: JPL P-29516 BW Range: 125, 000 kilometers (78,000 miles) Voyager 2's wide-angle camera captured this view of the outer part of the Uranian ring system just 11 minutes before passing though the ring plane. The resolution in this clear-filter view is slightly better than 9 km (6 mi). The brightest, outermost ring is known as epsilon. Interior to epsilon lie (from top) the newly discovered 10th ring of Uranus--designated 1986UR1 and barely visible here--and then the delta, gamma and...
